### What this PR does / why we need it?
Qwen3-235B-A22B belongs to the TopN model, but there is currently a lack
of care for the test cases of the wen3-235B-A22B model on Atlas A2, and
most of the machines currently owned by users in the community are A2.
When users encounter problems, we currently have no way of knowing
whether the model runs normally on the corresponding version of the
code, so we added it. In addition, we currently see TopN models such as:
qwen-dense, qwen3-30b-a3b, Qwen3-Next, Qwen2.5-Omni, but Qwen3-235B-A22B
is missing.
### Does this PR introduce _any_ user-facing change?

Overview
vLLM Ascend (vllm-ascend) is a community maintained hardware plugin for running vLLM seamlessly on the Ascend NPU.
It is the recommended approach for supporting the Ascend backend within the vLLM community. It adheres to the principles outlined in the [RFC]: Hardware pluggable, providing a hardware-pluggable interface that decouples the integration of the Ascend NPU with vLLM.
By using vLLM Ascend plugin, popular open-source models, including Transformer-like, Mixture-of-Expert, Embedding, Multi-modal LLMs can run seamlessly on the Ascend NPU.
Prerequisites
- Hardware: Atlas 800I A2 Inference series, Atlas A2 Training series, Atlas 800I A3 Inference series, Atlas A3 Training series, Atlas 300I Duo (Experimental)
- OS: Linux
- Software:
- Python >= 3.10, < 3.12
- CANN == 8.3.rc2 (Ascend HDK version refers to here)
